Functional expression of Cf9 and Avr9 genes in Brassica napus induces enhanced resistance to Leptosphaeria maculans. (1/396)

The tomato Cf9 resistance gene induces an Avr9-dependent hypersensitive response (HR) in tomato and transgenic Solanaceae spp. We studied whether the Cf9 gene product responded functionally to the corresponding Avr9 gene product when introduced in a heterologous plant species. We successfully expressed the Cf9 gene under control of its own promoter and the Avr9 or Avr9R8K genes under control of the p35S1 promoter in transgenic oilseed rape. We demonstrated that the transgenic oilseed rape plants produced the Avr9 elicitor with the same specific necrosis-inducing activity as reported for Cladosporium fulvum. An Avr9-dependent HR was induced in Cf9 oilseed rape upon injection of intercellular fluid containing Avr9. We showed Avr9-specific induction of PR1, PR2, and Cxc750 defense genes in oilseed rape expressing CJ9. Cf9 x Avr9 oilseed rape did not result in seedling death of the F1 progeny, independent of the promoters used to express the genes. The F1 (Cf9 x Avr9) plants, however, were quantitatively more resistant to Leptosphaeria maculans. Phytopathological analyses revealed that disease development of L. maculans was delayed when the pathogen was applied on an Avr9-mediated HR site. We demonstrate that the CJ9 and Avr9 gene can be functionally expressed in a heterologous plant species and that the two components confer an increase in disease resistance.  (+info)

Characterization of a functional soluble form of a Brassica napus membrane-anchored endo-1,4-beta-glucanase heterologously expressed in Pichia pastoris. (2/396)

The Brassica napus gene, Cel16, encodes a membrane-anchored endo-1,4-beta-glucanase with a deduced molecular mass of 69 kD. As for other membrane-anchored endo-1,4-beta-glucanases, Cel16 consists of a predicted intracellular, charged N terminus (methionine(1)-lysine(70)), a hydrophobic transmembrane domain (isoleucine(71)-valine(93)), and a periplasmic catalytic core (lysine(94)-proline(621)). Here, we report the functional analysis of Delta(1-90)Cel16, the N terminally truncated Cel16, missing residues 1 through 90 and comprising the catalytic domain of Cel16 expressed recombinantly in the methylotrophic yeast Pichia pastoris as a soluble protein. A two-step purification protocol yielded Delta(1-90)Cel16 in a pure form. The molecular mass of Delta(1-90)Cel16, when determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, was about 130 kD and about 60 kD after enzymatic removal of N-glycans, fitting the expected molecular mass of 59 kD. Delta(1-90)Cel16 was highly N glycosylated as compared with the native B. napus Cel16 protein. Delta(1-90)Cel16 had a pH optimum of 6.0. The activity of Delta(1-90)Cel16 was inhibited by EDTA and exhibited a strong dependence on calcium. Delta(1-90)Cel16 showed substrate specificity for low substituted carboxymethyl-cellulose and amorphous cellulose. It did not hydrolyze crystalline cellulose, xyloglycan, xylan, (1-->3),(1-->4)-beta-D-glucan, the highly substituted hydroxyethylcellulose, or the oligosaccharides cellotriose, cellotetraose, cellopentaose, or xylopentaose. Size exclusion analysis of Delta(1-90)Cel16-hydrolyzed carboxymethylcellulose showed that Delta(1-90)Cel16 is a true endo-acting glucanase.  (+info)

Multidrug resistance-like genes of Arabidopsis required for auxin transport and auxin-mediated development. (3/396)

Arabidopsis possesses several genes related to the multidrug resistance (MDR) genes of animals, one of which, AtMDR1, was shown to be induced by the hormone auxin. Plants having mutations in AtMDR1 or its closest relative, AtPGP1, were isolated by a reverse genetic strategy. Auxin transport activity was greatly impaired in atmdr1 and atmdr1 atpgp1 double mutant plants. Epinastic cotyledons and reduced apical dominance were mutant phenotypes consistent with the disrupted basipetal flow of auxin. The auxin transport inhibitor 1-naphthylphthalamic acid was shown to bind tightly and specifically to AtMDR1 and AtPGP1 proteins. The results indicate that these two MDR-like genes of Arabidopsis encode 1-naphthylphthalamic acid binding proteins that are required for normal auxin distribution and auxin-mediated development.  (+info)

Different myrosinase and idioblast distribution in Arabidopsis and Brassica napus. (4/396)

Myrosinase (EC 3.2.3.1) is a glucosinolate-degrading enzyme mainly found in special idioblasts, myrosin cells, in Brassicaceae. This two-component system of secondary products and degradative enzymes is important in plant-insect interactions. Immunocytochemical analysis of Arabidopsis localized myrosinase exclusively to myrosin cells in the phloem parenchyma, whereas no myrosin cells were detected in the ground tissue. In Brassica napus, myrosinase could be detected in myrosin cells both in the phloem parenchyma and in the ground tissue. The myrosin cells were similar in Arabidopsis and B. napus and were found to be different from the companion cells and the glucosinolate-containing S-cells present in Arabidopsis. Confocal laser scanning immunomicroscopy analysis of myrosin cells in B. napus embryos showed that the myrosin grains constitute a continuous reticular system in the cell. These findings indicate that in the two species studied, initial cells creating the ground tissue have different potential for making idioblasts and suggest that the myrosinase-glucosinolate system has at least partly different functions. Several myrosinases in B. napus extracts are recovered in complex together with myrosinase-binding protein (MBP), and the localization of MBP was therefore studied in situ. The expression of MBP was highest in germinating seedlings of B. napus and was found in every cell except the myrosin cells of the ground tissue. Rapid disappearance of the MBP from the non-myrosin cells and emergence of MBP in the myrosin cells resulted in an apparent colocalization of MBP and myrosinase in 7-d-old seedlings.  (+info)

Comparison of turnip crinkle virus RNA-dependent RNA polymerase preparations expressed in Escherichia coli or derived from infected plants. (5/396)

Turnip crinkle virus (TCV) is a small, plus-sense, single-stranded RNA virus of plants. A virus-coded protein, p88, which is required for replication has been expressed and purified from Escherichia coli. In vitro assays revealed that the recombinant p88 has an RNA-dependent RNA polymerase (RdRp) activity and can also bind to RNA. Deletion of the N-terminal region in p88 resulted in a more active RdRp, while further deletions abolished RdRp activity. Comparison of the E. coli-expressed p88, the N-terminal deletion mutant of p88, and a TCV RdRp preparation obtained from infected plants revealed that these preparations show remarkable similarities in RNA template recognition and usage. Both the recombinant and the plant TCV RdRp preparations are capable of de novo initiation on both plus- and minus-strand satC and satD templates, which are small parasitic RNAs associated with TCV infections. In addition, these RdRp preparations can efficiently recognize the related Tomato bushy stunt virus promoter sequences, including the minus- and plus-strand initiation promoters. Heterologous viral and artificial promoters are recognized poorly by the recombinant and the plant TCV RdRps. Further comparison of the single-component recombinant TCV RdRp and the multicomponent plant TCV RdRp will help dissect the functions of various components of the TCV replicase.  (+info)

Nitrogen storage and remobilization in Brassica napus L. during the growth cycle: identification, characterization and immunolocalization of a putative taproot storage glycoprotein. (6/396)

In taproot of oilseed rape (Brassica napus L.), a 23 kDa polypeptide has been recently identified as a putative vegetative storage protein (VSP) because of its accumulation during flowering and its specific mobilization to sustain grain filling when N uptake is strongly reduced. The objectives were to characterize this protein more precisely and to study the effect of environmental factors (N availability, daylength, temperature, water deficit, wounding) or endogenous signals (methyl jasmonate, abscisic acid) that might change the N source/sink relationships within the plant, and may therefore trigger its accumulation. The 23 kDa putative VSP has two isoforms, is glycosylated and both isoforms share the same N-terminal sequence which had been used to produce specific polyclonal antibodies. Low levels of an immunoreactive protein of 24 kDa were found in leaves and flowers. In taproot, the 23 kDa putative VSP seems to accumulate only in the vacuoles of peripheral cortical parenchyma cells, around the phloem vessels. Among all treatments tested, the accumulation of this protein could only be induced by abscisic acid and methyl jasmonate. When compared to control plants, application of methyl jasmonate reduced N uptake by 89% after 15 d, induced a strong remobilization of N from senescing leaves and a concomitant accumulation of the 23 kDa putative VSP. These results suggested that, in rape, the 23 kDa protein is used as a storage buffer between N losses from senescing leaves promoted by methyl jasmonate and grain filling.  (+info)

Functional significance of the alternative transcript processing of the Arabidopsis floral promoter FCA. (7/396)

The Arabidopsis gene FCA encodes an RNA binding protein that functions to promote the floral transition. The FCA transcript is alternatively processed to yield four transcripts, the most abundant of which is polyadenylated within intron 3. We have analyzed the role of the alternative processing on the floral transition. The introduction of FCA intronless transgenes resulted in increased FCA protein levels and accelerated flowering, but no role in flowering was found for products of the shorter transcripts. The consequences of the alternative processing on the FCA expression pattern were determined using a series of translational FCA-beta-glucuronidase fusions. The inclusion of FCA genomic sequence containing the alternatively processed intron 3 restricted the expression of the transgene predominantly to shoot and root apices and young flower buds. Expression of this fusion also was delayed developmentally. Therefore, the alternative processing of the FCA transcript limits, both spatially and temporally, the amount of functional FCA protein. Expression in roots prompted an analysis of root development, which indicated that FCA functions more generally than in the control of the floral transition.  (+info)

Nitrogen storage and remobilization in Brassica napus L. during the growth cycle: effects of methyl jasmonate on nitrate uptake, senescence, growth, and VSP accumulation. (8/396)

The role of methyl jasmonate (MeJa) in promoting senescence has been described previously in many species, but it has been questioned in monocarpic species whether induced senescence is a result of a potential death hormone like MeJa, or a consequence of an increased metabolic drain resulting from the growth of reproductive tissue. In oilseed rape (Brassica napus L.), a polypeptide of 23 kDa has been recently identified as a putative vegetative storage protein (VSP). This polypeptide could be used as a storage buffer between N losses from senescing leaves putatively promoted by methyl jasmonate that might be produced by flowers, and grain filling which occurs later on, while N uptake is strongly reduced. In order to describe causal relationships during Brassica napus L. plant responses to MeJa treatment, a kinetic experiment was performed to determine the order and the amplitude with which general processes such as growth, photosynthesis, chlorophyll content, N uptake, and N storage under the form of the 23 kDa VSP are affected. One of the most immediate consequences of MeJa treatment was the strong reduction of nitrate uptake within 6 h, relative to control plants. However, this was not a specific effect as K(+) uptake was similarly affected. Photosynthesis was reduced later (after 24 h), while chlorophyll content as well as leaf growth also decreased in a similar way. Moreover, this was concomitant with a remobilization of endogenous unlabelled N from senescing leaves to roots. Accumulation of the 23 kDa VSP was induced in the taproot after 24 h of MeJa treatment and was increased 10-fold within 8 d. On the other hand, the reversible effect of a MeJa pretreatment was tested in the long term (i.e. along the growth cycle) using plants previously grown in field conditions induced for flowering. Results show that a MeJa pulse induced a reversible effect on N uptake inhibition. In parallel, protein immunologically related to the 23 kDa VSP was detected in stems with a similar molecular weight (23 kDa), and in flowers and leaves with a molecular weight of 24 kDa. This accumulation was concomitant with the remobilization of both subunits of Rubisco. During stem and pod development, this protein induced by MeJa is fully hydrolysed. The external and intermittent supply of MeJa mimic some of the plant physiological processes previously reported under natural conditions. This suggests that in oilseed rape, methyl jasmonate could be considered as a possible monocarpic senescence factor while accumulation/mobilization of the 23 kDa VSP in taproot could be a marker for the cessation of N uptake and the initiation of a massive leaf senescence.  (+info)

The rape stem weevil, Ceutorhynchus napi Gyll., is a serious pest of winter oilseed rape (Brassica napus L.) crops in Europe causing severe yield loss. In currently used oilseed rape cultivars no resistance to C. napi has been identified. Resynthesized lines of B. napus have potential to broaden the genetic variability and may improve resistance to insect pests. In this study, the susceptibility to C. napi of three cultivars, one breeding line and five resynthesized lines of oilseed rape was compared in a semi-field plot experiment under multi-choice conditions. Plant acceptance for oviposition was estimated by counting the number of C. napi larvae in stems. The larval instar index and the dry body mass were assessed as indicators of larval performance. The extent of larval feeding within stems was determined by the stem injury coefficient. Morphological stem traits and stem contents of glucosinolates were assessed as potential mediators of resistance. The resynthesized line S30 had ...

N1 - Includes bibliographical references.. PY - 2018/11/5. Y1 - 2018/11/5. N2 - Rapeseed (canola, Brassica napus L.) is the second major oilseed crop of the world and provides a source of healthy oil for human consumption, meal for stock markets and several other by-products. Several weed species afflict the sustainable production and quality of canola. Various agronomic practices such as crop rotation, stubble management (e.g. burn-ing), minimum tillage, application of herbicides and cultivation of herbicide resistant varie-ties have been deployed to minimise yield losses. There is no doubt that herbicide-tolerant cultivars enable management of weeds which are difficult to control otherwise. However, widespread usage increases the risk of herbicide resistance. This is becoming a major imped-iment in sustaining high crop ...

Blackleg caused by Leptosphaeria maculans is a widespread fungal disease on B~assica napus (oilseed rape). In contrast, Arabidopsis thaliana and B. nigra are in general highly resistant. This study presents results from genomic interaction between the A. thaliana and B. napus genome with focus on L. maculans resistance. Identification and partial characterization of A. thaliana resistance in accessions, L. maculans susceptible mutants, and signaling pathways were also performed. Finally, a resistance gene to L. maculans from B. nigra was cloned and transferred to B. napus. Chromosome counts and RFLP analyses of A. thaliana DNA content in A. thaliana (+) B. napus back-crossed progeny were performed. The results showed that in BC,, originating from symmetric hybrids, the frequency of retained A. thaliana loci was reduced to 42%. The average chromosome number decreased from 48 in BC1 to 39 in BC2. These results can be compared with the asymmetric hybrid derived BC,, that had 16% loci present and an ...
Seed was sown in Metro Mix Soil in flats containing 14 rows of seven cells each (cells were ∼3.81 cm in diameter and ∼20 cm deep). Flats were organized into two replicate blocks in a 1002 foot indoor grow room at the University of Wisconsin Biotron Facility. Outer rows of each flat were seeded with border plants, and each of the remaining inner 12 rows were seeded in random order with an individual S0, S5, or parental line of B. rapa or B. oleracea (each cell was double seeded and thinned to one plant). Each block contained 10 flats, and each line was represented once per block. Within each block, the positions of flats were randomized daily. Plants were watered daily and fertilized every other day with dilute (1 tableapoon/20 liters) Peters Professional Peat Lite Special 20-10-20. Temperature was maintained at 21°C, humidity at 60%, and light maintained at ∼450 μmol/m2/s−1 for 16 h each day..

Polyploidy (i.e., whole genomic duplication) has played a significant role in the evolutionary history of all eukaryotes (1), and particularly in flowering plants (2). It is estimated that most flowering plants are polyploid, including most agricultural crops (3-7). Although all angiosperms have experienced at least one round of whole-genome duplication during their evolution, they have undergone diploidization (8-10). The structural evolution of genomes in ancient polyploids included reductions in chromosome number, chromosome fusions, and various types of chromosomal rearrangements (8, 11). Studies on newly resynthesized Brassica napus and recently formed polyploids of Tragopogon suggest that genomic changes occur rapidly following allopolyploidization in some plant species (12-14). Allopolyploidization can result in chromosomal rearrangements, DNA methylation changes, chromatin remodeling, changes in gene expression, and activation of transposable elements (13-22). Cytogenetic studies using ...
Leucine-rich repeat receptor-like proteins (LRR-RLPs) are highly adaptable parts of the signalling apparatus for extracellular detection of plant pathogens. Resistance to blackleg disease of Brassica spp. caused by Leptosphaeria maculans is largely governed by host race-specific R-genes, including the LRR-RLP gene LepR3. The blackleg resistance gene Rlm2 was previously mapped to the same genetic interval as LepR3. In this study, the LepR3 locus of the Rlm2 Brassica napus line Glacier DH24287 was cloned, and B. napus transformants were analysed for recovery of the Rlm2 phenotype. Multiple B. napus, B. rapa and B. juncea lines were assessed for sequence variation at the locus. Rlm2 was found to be an allelic variant of the LepR3 LRR-RLP locus, conveying race-specific resistance to L. maculans isolates harbouring AvrLm2. Several defence-related LRR-RLPs have previously been shown to associate with the RLK SOBIR1 to facilitate defence signalling. Bimolecular fluorescence complementation (BiFC) and ...
The inaccessibility of the zygote and proembryos of angiosperms within the surrounding maternal and filial tissues has hampered studies on early plant embryogenesis. Somatic and gametophytic embryo cultures are often used as alternative systems for molecular and biochemical studies on early embryogenesis, but are not widely used in developmental studies due to differences in the early cell division patterns with seed embryos. A new Brassica napus microspore embryo culture system, wherein embryogenesis highly mimics zygotic embryo development, is reported here. In this new system, the donor microspore first divides transversely to form a filamentous structure, from which the distal cell forms the embryo proper, while the lower part resembles the suspensor. In conventional microspore embryogenesis, the microspore divides randomly to form an embryonic mass that after a while establishes a protoderm and subsequently shows delayed histodifferentiation. In contrast, the embryo proper of ...

Comparison of Response of Canola (Brassica napus L. cv Hyola 401) to Biofertilizer Inoculation in Optimal and Delayed Cropping Dates
Although rapeseed (Brassica napus L.) is known to be affected by waterlogging, the genetic basis of waterlogging tolerance by rapeseed is largely unknown. In this study, the transcriptome under 0 h and 12 h of waterlogging was assayed in the roots of ZS9, a tolerant variety, using digital gene expression (DGE). A total of 4432 differentially expressed genes were identified, indicating that the response to waterlogging in rapeseed is complicated. The assignments of the annotated genes based on GO (Gene Ontology) revealed there were more genes induced under waterlogging in

Environmental concerns over the cultivation of Genetically Modified (GM) crops largely centre on the ecological consequences following gene flow to wild relatives. One attractive solution is to deploy biocontainment measures that prevent hybridization. Chloroplast transformation is the most advanced biocontainment method but is compromised by chloroplast capture (hybridization through the maternal lineage). To date, however, there is a paucity of information on the frequency of chloroplast capture in the wild. Oilseed rape (Brassica napus, AACC) frequently hybridises with wild Brassica rapa (AA, as paternal parent) and yields B. rapa-like introgressed individuals after only two generations. In this study we used chloroplast CAPS markers that differentiate between the two species to survey wild and weedy populations of B. rapa for the capture of B. napus chloroplasts. A total of 464 B. rapa plants belonging to 14 populations growing either in close proximity to B. napus (i.e. sympatric 1 km) were ...
SUTs drive translocation of sucrose and in turn affect seed yield and fruit size [18, 37]. In another study carried out in our laboratory, identification of yield-related QTLs in a B. napus functional map [38] indicated that a functional marker from SUT in the A7 linkage group was related to EFB, SP, and TSW in the A7 linkage group [31, 39]. Here, we report likely polymorphisms in BnA7.SUT1 associated with yield-related traits, and allelic variation at the promoter and CDS of BnA7.SUT1 correlated with expression pattern and phenotype. Polymorphisms at the promoter and CDS regions with an effect on expression abundance are likely candidates for causative QTPs [40, 41]. Similarly, allelic polymorphism at the promoter and intron of HvFT1 in barley contribute to variation in flowering time [35]..

Brassica napus provides approximately 13-16% of global vegetable oil for human consumption and biodiesel production. Plant height (PH) is a key trait that affects plant architecture, seed yield and harvest index. However, the genetic mechanism of PH in B. napus is poorly understood. A dwarf mutant df59 was isolated from a large-scale screening of an ethyl methanesulphonate-mutagenized rapeseed variety Ningyou 18. A genetic analysis showed that the dwarfism phenotype was controlled by one semi-dominant gene, which was mapped on C9 chromosome by quantitative trait loci sequencing analysis and designated as BnaDwf.C9. To fine-map BnaDwf.C9, two F2 populations were constructed from crosses between conventional rapeseed cultivars (Zhongshuang 11 and Holly) and df59. BnaDwf.C9 was fine-mapped to the region between single-nucleotide polymorphism (SNP) markers M14 and M4, corresponding to a 120.87-kb interval of the B. napus Darmor-bzh genome. Within this interval, seven, eight and nine annotated or predicted
MAIN CONCLUSION : Small RNAs and microRNAs were found to vary extensively in synthetic Brassica napus and subsequent generations, accompanied by the activation of transposable elements in response to hybridization and polyploidization. Resynthesizing B. napus by hybridization and chromosome doubling provides an approach to create novel polyploids and increases the usable genetic variability in oilseed rape. Although many studies have shown that small RNAs (sRNAs) act as important factor during hybridization and polyploidization in plants, much less is known on how sRNAs change in synthetic B. napus, particularly in subsequent generations after formation. We performed high-throughput sequencing of sRNAs in S₁-S₄ generations of synthetic B. napus and in the homozygous B. oleracea and B. rapa parent lines. We found that the number of small RNAs (sRNAs) and microRNAs (miRNAs) doubled in synthetic B. napus relative to the parents. The proportions of common sRNAs detected varied from the S₁ to ...

The role of phosphatidylcholine (PC) in fatty acid exchange and desaturation was examined and compared with that of monogalactosyldiacylglycerol (MGDG) in Brassica napus leaves using 14C-labelling in vivo. Data are presented which indicate that in the chloroplast newly formed saturated (palmitic acid, 16:0) and monounsaturated (oleic acid, 18:1) fatty acid is incorporated into MGDG and desaturated in situ. In the non-plastidic compartments, however, newly formed fatty acid is exchanged with polyunsaturated fatty acid in PC, the probable major site of subsequent desaturation. The unsaturated fatty acid is released to the acyl-CoA pool, which is then used to synthesize diacylglycerol (DAG) containing a high level of unsaturated fatty acid. This highly unsaturated DAG may be the source for the biosynthesis of other cellular glycerolipids. The generally accepted pathway in which PC is synthesized from molecular species of DAG containing 16:0 and 18:1 followed by desaturation of the 18:1 to linoleic ...
Map-based cloning of quantitative trait loci (QTLs) in polyploidy crop species remains a challenge due to the complexity of their genome structures. QTLs for seed weight in B. napus have been identified, but information on candidate genes for identified QTLs of this important trait is still rare. In this study, a whole genome genetic linkage map for B. napus was constructed using simple sequence repeat (SSR) markers that covered a genetic distance of 2,126.4 cM with an average distance of 5.36 cM between markers. A procedure was developed to establish colinearity of SSR loci on B. napus with its two progenitor diploid species B. rapa and B. oleracea through extensive bioinformatics analysis. With the aid of B. rapa and B. oleracea genome sequences, the 421 homologous colinear loci deduced from the SSR loci of B. napus were shown to correspond to 398 homologous loci in Arabidopsis thaliana. Through comparative mapping of Arabidopsis and the three Brassica species, 227 homologous genes for seed size

Pretreatment of the first true leaves of oilseed rape plants (Brassica napus cv. Bristol) with menadione sodium bisulphite (MSB) locally and systemically induced resistance, as shown by reduced lesion size and number, to infection by the fungal pathogen Leptosphaeria maculans, the causal agent of stem canker. Using a known systemic activator of salicylic acid-dependent PR-1 induction, acibenzolar-S-methyl (BTH; S-methylbenzo[1,2,3]thiadiazole-7-carbothiate) as a comparison, real-time PCR expression analysis of genes encoding a pathogenesis-related protein 1 (PR-1) and an ascorbate peroxidase (APX) demonstrated a systemic enhancement of APX expression in MSB-pretreated plants, with no effect on PR-1 expression, suggesting augmented reactive oxygen species production in MSB-pretreated plants. The results demonstrate MSB to be an effective resistance activator in oilseed rape, and potentially useful for the control of stem canker ...
The sequences of Brassica napus L. pollen oleosins have been determined and examined. Contrary to a recent report, inferred primary sequences of pollen oleosins do include a unique C-terminal domain characterised by the presence of a repetitive motif of three alanine and one proline residue (AAAP). This motif appears to be present in all oleosins expressed in pollen, but not in oleosins from other tissues.. ...
Major interest has focused on the identification of regulatory factors involved in lipid biosynthesis. This study examined the B.napus β-Keto-ACP reductase 5 sequence for potential regulatory cis-acting elements. The 5 sequence of the most highly expressed Brassica napus β-Keto-ACP reductase isoform was fused to the reporter gene β-glucuronidase (GUS) and its expression pattern examined within transgenic Arabidopsis. The construct was shown to act as a functional promoter and direct transcription within embryos, cotyledons and roots. There was no apparent staining within the true leaves, but staining was visible within the cotyledons. Overlapping fragments of the promoter were analysed in gel mobility shift assays and all six showed the formation of protein-DNA complexes. Competition analysis suggested that the same trans-acting factor binds to a number of regions along the promoter. The protein-DNA complex appeared to be competed away by the Arabidopsis enoyl-ACP reductase (EnR) promoter ...
The I3 cDNA isolated from a library made from 2-4 mm (immature) anthers of Brassica napus shows microspore-specific expression. Homologous transcripts are detected in buds and anthers of male-fertile plants, but not in green tissues, roots, or in cytoplasmic male-sterile buds. High expression of the transcript is limited to microspores entering and undergoing mitosis. The predicted peptide sequence of the cDNA shows an unusual repeated alanine/proline motif at the C-terminus, which may be of importance in the native protein structure.. ...

Three members of Brassica napus TRANSPARENT TESTA 2 (BnTT2) gene family encoding potential R2R3-MYB regulatory proteins of proanthocyanidin biosynthesis were isolated. BnTT2-1, BnTT2-2, and BnTT2-3 are 1102 bp with two introns, and have a 938-bp full-length cDNA with a 260 amino acid open reading frame. They share 98.2-99.3% nucleotide and 96.5-98.5% amino acid identities to each other, and are orthologous to Arabidopsis thaliana TT2 (AtTT2) with 74.1-74.8% nucleotide and 71.1-71.8% amino acid identities. An mRNA type of BnTT2-2 was found to contain unspliced intron 2 and encode a premature protein. They all have an alternative polyadenylation site. BnTT2-1 and BnTT2-3 also have an alternative transcription initiation site. Aligned with AtTT2, their 5 untranslated regions (UTRs) are astonishingly conserved, and two conserved regions were also found in their 3 UTRs. Oligonucleotide deletion leads to double-start codons of them. Resembling AtTT2, BnTT2 proteins are nuclear-located R2R3-MYB ...

Brassica is the most economically important genus in the Brassicaceae family. Among Brassica crops, oilseeds have the highest economic value, reflected in the fatty acid composition of the oil. Resistance to fungal pathogens and insect pests is frequently investigated in the selection of Brassicas. Cultivars resistant to Sclerotinia would be desirable for both ecological and economic reasons. Cabbage seedpod weevil and root maggot could be controlled by introgression of resistance genes and analysis of qualitative traits. Haploids of rapeseed are used to produce haploid calli for in vitro mutation selection. Homozygous rapeseed plants are generated by culturing microspores from flower buds of F1 plants. The doubled haploid production system enables breeders to develop homozygous genotypes from heterozygous parents in one generation. Since the development of canola, rapeseed low in erucic acid and glucosinolates, research has shifted towards reduction of linolenic acid. Finally, selection ...
Winter oilseed rape is characterized by a low N use efficiency related to a weak leaf N remobilization efficiency (NRE) at vegetative stages. By investigating the natural genotypic variability of leaf NRE, our goal was to characterize the relevant physiological traits and the main protease classes associated with an efficient proteolysis and high leaf NRE in response to ample or restricted nitrate supply. The degradation rate of soluble proteins and D1 protein (a thylakoid-bound protein) were correlated to N remobilization, except for the genotype Samouraï which showed a low NRE despite high levels of proteolysis. Under restricted nitrate conditions, high levels of soluble protein degradation were associated with serine, cysteine and aspartic proteases at acidic pH. Low leaf NRE was related to a weak proteolysis of both soluble and thylakoid-bound proteins. The results obtained on the genotype Samouraï suggest that the timing between the onset of proteolysis and abscission could be a determinant. The
Chitosan oligosaccharides (collectively, oligochitosan, or COS) are considered to be potent plant immunity elicitors. In this article, the induction of resistance to Sclerotinia sclerotiorum in Brassica napus L. var. Huyou 15 by COS is studied. Even though COS (50 mu g mL(-1)) did not affect radial growth of this pathogen in vitro, it reduced the disease symptoms in vivo relative to control plants. The disease control rates were 25.8%, 41.4%, 57.1%, 68.7%, and 48.8% with COS pretreatment 0, 24, 48, 72, and 96 h before S. sclerotiorum inoculation, respectively. Specific binding of COS to B. napus epidermis cells was validated by competition experiments. Simultaneously, it was observed that COS induced bursts of cytosolic Ca2+, nitric oxide (NO), and hydrogen peroxide (H2O2). NO and H2O2 inhibitors were used to prove the interaction between NO and H2O2. Furthermore, treatments of B. napus with NO and H2O2 inhibitors reduced the induction effect of the jasmonic acid-ethylene (JA/ET) signaling ...
By HELGE NEUMANN, RALF LOGES und FRIEDHELM TAUBE, Kiel. Due to the continuously increasing number of biogas plants in Germany, the area cultivated with silage maize Zea mays has been increasing significantly over the past few years. From the viewpoint of nature conservation it is generally supposed that this change in land use could result in losses of habitats of wild plant and animal species. In this paper we present the results of a study conducted in the federal state of Schleswig-Holstein in Northern Germany over the period 2005 to 2007. Paired comparisons of single arable fields were used to analyse whether silage maize fields were characterized by other bird communities than fields cultivated with common cash crops (winter cereals, winter oilseed rape). Birds were recorded during the breeding time as well as during the non-breeding time.. Maize fields and cash crop fields showed similar numbers of breeding bird species. Lapwings Vanellus vanellus occurred more often in maize fields, ...

Rapeseed (B. napus, AACC, 2n = 38) is one of the most important oil seed crops in the world, it is also one of the most common oil for production of biodiesel. Its oil is a mixture of various fatty acids and dissection of the genetic network for fatty acids biosynthesis is of great importance for improving seed quality. The genetic basis of fatty acid biosynthesis in B. napus was investigated via quantitative trail locus (QTL) analysis using a doubled haploid (DH) population with 202 lines. A total of 72 individual QTLs and a large number pairs of epistatic interactions associated with the content of 10 different fatty acids were detected. A total of 234 homologous genes of Arabidopsis thaliana that are involved in fatty acid metabolism were found within the confidence intervals (CIs) of 47 QTLs. Among them, 47 and 15 genes homologous to those of B. rapa and B. oleracea were detected, respectively. After the QTL mapping, the epistatic and the candidate gene interaction analysis, a potential regulatory
Targeted genomic selection methodologies, or sequence capture, allow for DNA enrichment and large-scale resequencing and characterization of natural genetic variation in species with complex genomes, such as rapeseed canola ( Brassica napus L., AACC, 2n=38). The main goal of this project was to combine sequence capture with next generation sequencing (NGS) to discover single nucleotide polymorphisms (SNPs) in specific areas of the B. napus genome historically associated (via quantitative trait loci -QTL- analysis) to traits of agronomical and nutritional importance. A 2.1 million feature sequence capture platform was designed to interrogate DNA sequence variation across 47 specific genomic regions, representing 51.2 Mb of the Brassica A and C genomes, in ten diverse rapeseed genotypes. All ten genotypes were sequenced using the 454 Life Sciences chemistry and to assess the effect of increased sequence depth, two genotypes were also sequenced using Illumina HiSeq chemistry. As a result, 589,367 ...

We examined several environmental and developmental influences on trypsin inhibitor (TI) activity in leaves of young Brassica napus seedlings in a series of greenhouse experiments. In seedlings of B. napus cv. Westar, TI activity is constitutively present and exhibits a rise then fall through time in the first true leaves of young plants. TI activity is induced by wounding in the first true leaves, but the degree of induction is relatively insensitive to the degree of wounding over a gradient of 5-15% of leaf area damage. TI activity is enhanced in first true leaves of plants in which the cotyledons have been wounded relative to plants in which the cotyledons have not been wounded. TI activity is also enhanced in the second true leaves on plants in which the first true leaves have been wounded. The degree of systemic induction in second true leaves declines additively with plant age, but local induction in the first true leaves is not affected by age. In B. napus cv. Gido, TI activity is constitutively
Rapeseed (Brassica napus), also known as rape, oilseed rape, rapa, rappi, rapaseed (and, in the case of one particular group ofcultivars, canola), is a bright yellow flowering member of the family Brassicaceae (mustard or cabbage family). The name derives from the Latin for turnip, rapa or rapum, and is first recorded in English at the end of the 14th century. Older writers usually distinguished the turnip and rape by the adjectives round and long(-rooted), respectively.See also Brassica napobrassica, which may be considered a variety of Brassica napus.
Here, the allotetraploid species Brassica napus L. is a global crop of major economic importance, providing canola oil (seed) and vegetables for human consumption and fodder and meal for livestock feed. Characterizing the genetic diversity present in the extant germplasm pool of B. napus is fundamental to better conserve, manage and utilize the genetic resources of this species. We used sequence-based genotyping to identify and genotype 30,881 SNPs in a diversity panel of 782 B. napus accessions, representing samples of winter and spring growth habits originating from 33 countries across Europe, Asia, and America. We detected strong population structure broadly concordant with growth habit and geography, and identified three major genetic groups: spring (SP), winter Europe (WE), and winter Asia (WA). Subpopulation-specific polymorphism patterns suggest enriched genetic diversity within the WA group and a smaller effective breeding population for the SP group compared to WE. Interestingly, the ...
